This invention relates to protective mechanisms tion, the dog of the locking device comes into embodying safety provisions.

This invention has utility when incorporated in safeguards, especially of receptacles against unauthorized attack. Primarily there are features of locking, not only as effective for time delay against unlocking, but also indicate the unlocked or opened condition. This indication may be used for a bank tellers cage cash reserve as a signal for the cashier or other bank supervisor. Furthermore there is definite manual control selectively in sequence for further safeguarding, such as by signal to police or American District Telegraph.

Referring to the drawings:

Floor in a tellers cage need not be cluttered with burglar warning means. Receptacle 2 on such fioor is provided with counter height top 3. The receptacle 2 has a vertical side opening 4, to one side of which are hinges 5, swingably mounted closure 6. Spindle l as rockable is effective through arm 8 to act on vertical bar 9 to shift such bar horizontally toward the hinges 5 and thus withdraw closure-releasing bolts or safe-guarding means H). The door 6 is thus freed for opening.

On the inner side of the mounted lock box closure 6 (Fig. 2) is H having closure plate |2 rethereto by bolts I3. Control of the locking devices through spindle I4 which is adjacent the spindle l. Graduations l5 at the spindle M are guiding to the one knowing the combination for placing tumblers IE to have notches l7 align. Lateral lug |8 from dog or pawl l9 may enter these notches W as the dog l3 swings on its pivot bearing 20. Pivot bearing 20 is in member 2|. The member 2| is horizontally slidable in guides 22, 23, fixed with the lock box Notch 24 on the lower side of the dog l3 thus comes down into the range of pin 25 on disk 26 fixed with the spindle l4. At the tumbler notch alignment as the predetermined unlocked posithe control of the operator of the spindle l4, and. the slidable member 2| of this unlocker may be controllably moved.

l6, and should there be attack attempt by forcing inward the spindle l4 and the disk 26, the arm 21 would be shifted about the screw 28 as a fulcrum. Nor would such attack bring the dog I9 into the notches IT to permit movement of the Arm 21, mounted by screw, 28 in the box II, is in position againsta tumbler Switch 32 is mounted by nuts 33 in adjustably to locate .switch operatspring plate 35 with the bolt 2| to protrude there-.

below.

Spring 3'! acts upon the plunger 34 normally to thrust such plunger toward the member 2|. Rather stiff spring terminus 38 for the lower portion of the plate 35 is curved away from the box Accordingly, as the member 2| shifts into the box II, this terminus 38 acts as a cam upon plunger 39 to thrust such against the action of its spring 40, and thus acts on second switch 4| mounted by nuts 42 in the lower arm of the bracket 3|. Each switch is accordingly adjustable as to the bracket 3 I, and the bracket 3| is adjustable as to the box Notch 43 in the lower side of the member 2| is engaged by tapered end of plunger 44 as yieldably urged by helical spring 45. This provides a yieldable resistance to the shifting of the member 2| as the switch 32 is operated and before the switch 4| has been actuated in sequence thereafter.

In normal operation, the plunger 44 is limited in its movement into the notch 43 by the arm 27. However, if the spindle I4 is driven in in an unauthorized attack, the arm 21, swinging on its fulcrum 28, is thrown clear of the shoulder on the bolt 44, thus allowing the spring 45 to move the bolt 44 into the notch 43 to lock the member 2| against movement.

Electrical features of safe-guarding are cooperative herein. Electric power supply lines 48, 41, extend to fitting or plug 48 (Fig. '7). From this fitting 48, the line 46 has connection by way of line 49 with fitting or plug 50, and therefrom by line 5| to the switch 32 as first in the sequence for action thereon by the member 2| From the switch 32 this line 5| has connection by way of line 52 to the fitting 50 independently of the line 49, thence by line 53 to the fitting. 48 independently of the line 46, and therefrom by way of line 54 to electric mechanism 55, herein shown as a signal visible to the cashier or other bank supervisor for the teller or one whose duty it is to handle the receptacle 2 for safety. From the fitting 48 and connected with the line 41 is line 56 to the electric bulb or signal 55. As the operator of the spindle l4 has the lock device in 5 predetermined assembly of the tumblers l6 to effect initial shifting of the member 2|, there is safe-guarding warning of such condition at the mechanism 55. Should the operator be lax in not using the receptacle for protection, such 10 laxity is indicated at the light 55 for warning to the operator.

Closing of the switch 32 additionally connects the line 5| with line 51, extending to time delay mechanism in housing 58' (Fig. 2) herein shown as mounted in the closure 8. Manually adjustable arm 59 is located as a predetermined time control or position on scale 69, and is there effective through adjustable arm conductor 6| from the line 51 to extend to line 62 and the synchronous motor 63, circuit through which is completed by line 64 (Fig. 1) to fitting 59, line 65 to fitting 48, and there connected to the line 41.

Between the lines 51, 64, is coil 65. Closing of the switch 32 energizes the coil 66, which thereby connects the transmission means 61 to be actuated by the motor 63. This operation of the transmission results in shifting of the pointer 68 along the scale 68. The pointer 68 is eifective at adjustably located switch 69 to connect line 10 from the line 52 with line 1| extending to coil 12 connected by line 13 with the line 64. The coil 12 is thus placed in parallel with the motor timer 63 as such motor is still running and the gearing means 61 is clutched, for an effective current to be taken by the coil 12 operative to withdraw bolt or release 14 (Figs. 2, 3, '1) from holding position as to the bolt I0, thereby allowing the spindle 1 to function in operating the bolts H] to release position.

Spring 15 is effective at de-energized condition of the coil 12 to hold the bolt 14 against the side of the bolt Hi. It thus follows that any throwing of the bolts ID to locking position when the current is not energizing the coil 12, allows the bolt 14 to come to effective locking position to keep such bolts l0 thrown.

By releasing latch 16 (Fig. 2), closure plate 11 may be swung downward, and the arm 59 reset for a desired subsequent time-delay or lag in permitting opening of the closure. The member 2| does not permit its release to be forthwith operable until the electric motor mechanism of the synchronous motor 63 has run its cycle as predetermined in the manual setting of the arm 59 as to the scale 69. When there has elapsed the timed release so that the coil 12 is energized, then the bolt 14 may be withdrawn to permit operation of the spindle 1 and withdrawal of the bolts lo.

0 By placing the electric signal mechanism 55 in parallel with the time delay mechanism 58, there is effective inter-relation brought about by the three lines from the fittings 48, 58, or both thereof, of safe-guarding value herein for 5 delay, or immediacy of the remote signal, for the delay be definite as brought about by the functioning of the mechanism 58.

While there are two fittings 48, 56, and two mechanisms 55, 58, additionally there are two 7 switches at the bolt 2|, the switch 32, and the switch 4|. Lines 18, 19, from the switch 4| extend to plug or fitting 88 (Fig. '1) adjacent the fitting 58 (Fig. 2) as mounted in the closure 6. Lines 8|, 82, from the fitting 88 extend to fitting 83 in outlet box 84 adjacent the fitting 48 (Figs.

1, 7). The box 84 may be on wall 85 and remotely therefrom is located police warning or mechanism 86, connected by lines 81, 88, with the fitting 83. The line 81 is connected to power line 41. The line 88 is connected to coil 89 and has its circuit therefrom completed by line 90 to the electric current supply line 46. Switch 4| as normally closed has'the coil 89 energized to keep switch 9| open; As the switch 4| is opened, the coil 89 is de-energized; the switch 9| closes. Energy source or battery 92 has line 93 therefrom to the switch 9|, which switch as closed connects by line 94 to signal or alarm 95 as a warning mechanism with the circuit therefrom completed by line 96 to the battery 92. This electric mechanism is self-resetting as the bolt 2| is shifted toward unthrown position or toward the switch 32, thereby permitting the switch 4| to close switch 9|. Switch 91 in the line 98 may be operated manually from time to time for thereby opening and closing the circuit including the coil 89 when the switch 4! is closed. Then with the coil 89 energized the alarm 95 should be sounded.

Fixed with the arm 68 on shaft 91 is cam 98 effective as the continued operation of the motor 63 shifts the arm 59 and the closed switch 69, further to move the cam 98. This cam 98 is accordingly a motor actuated control effective after a time interval following the closing of the switch 69 to act on switch 99 as a stop in opening the circuit in the line 51. The arm 68 may have been set or reset manually to run say fifteen minutes to close the control part or switch 89. The cam 98 may be adjusted to act upon the switch 99 in say three minutes after the switch 69 was closed. This means that as the switch 99 is opened the motor 63 stops, the coil 12 is de-energized so that the bolt 14 is again thrown to locking position by the spring 15, and the coil 66 is de-energized to unclutch the motor 63 from driving the arm 68 through the differential or speed reduction gearing 61. Torsion spring I99 on the shaft 91 is then at once effective to reset the arm 68 as the bolt 14 is returned to locking position.

When the door 6 is open, pin |9| (Fig. 3) from the bolt 14 projects through opening I02 in rear cover plate N13 for the door 6. The attendant may manually release the spindle 1 by operating the pin |8| to hold the bolt 14 against the action of the spring 15.

When the door 6 is open, switch I84 (Figs. 2, 7) between the lines 5|, 52, is closed, thereby giving warning signal at the light 55. When the spingle 1 is at bolt unlocking position, switch I05 is in closed position between the lines 5|, 52, also serving to light up the signal 55. Therefore, at any time when the time delay mechanism is operated, if there be opening action, it is signaled should there be unsafeguarded condition as through open door 6 or as through locking bolts ID. If the door be closed and the bolts not withdrawn, the cam 98 is eifective to relock the mechanism.
